CHRISTIAN H. SALZMAN, OF CHICAGO, ILLINOIS.

GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 403,385, dated May 14, 1889.

Application filed June 19, 1886. Serial No. 205,668. (No model.)

To all whom it may concern:

Be it known that I, CHRISTIAN H. SALZMAN, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented certain new and useful Improvements in Grain-Binders, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation, with the breastplate partly broken away. Fig. 2 is a plan view looking from the front; Fig. 3, a vertical section on line @c @c of Fig. 4; Fig. 4, a plan view looking from the front, showing the parts in their changed relation to each other from that shown in Fig. 2; Fig. 5, a detail of the disk-frame; Fig. 6, a front view, with part of the supporting-frames and knife-arm broken away; Fig. 7, a detail showing the cam for operating the knife-arm. Fig. S is a detail view of the knotter.

The object of this invention is to simplify the construction of a self-binding harvestingmachine knotter mechanism, to make its operation easier, and to improve its action by relieving it from sudden strain or jerks; and its nature consists in the several improvements hereinafter described and claimed as new.

In the drawings, A indicates the breastplate; A', needle-slot through the breastplate; B, discharge-board; C C', braces; D D' D", knotter stand or frame; E, brace ;l F, knotter cam-wheel; F', its hub; G, gear-teeth for operating the pinion; H H', cam-wheel and cam-groove for operating the knife-arm; I I', discharge-arms; J K, cam on cam-wheel F; L L' M N, knife-arm; O, knotter-bill; P, disk-frame; Q, disk; R,rocker-arm; S S', diskspring or cord-holder; T, knotter-driving or power shaft; co, knife-arm pivot; b, anti-friction roller on knife-arm L; c, notch or opening in knife-arm for the passage of the knotter-bill; d, cord-passage through knife-arm; e, projection or shoulder for attaching a spring to the knife-arm; f, spring; g, pin for moving the hinged jaw of the knotter-bill; h, knotterbill pinion; t', inner flange on wheel F; c", flattened space on knotter-pinion; j j', bearings on the knetter-frame for supporting the kn otter-bill; k, anti-friction-wheel on the outer end of the hinged jaw of the knotter-bill; Z,

knife; m, projection on knotter-stand co-operating with the knife; a, depressions, and 0 ridge or scroll tooth on the wheel F for operating the disk Q.

The breast-plate A, wit-h its needle-slot A', is made in the usual form and provided with the extension or board B, to insure the discharge of the bound bundle in the ordinary manner.

The knetter stand or frame D is made as shown. It is provided with the bearings D D" for supporting the knotter-shaft, and also with the bearings j j' for the shaft of the knotter-pinion h. This knotter-stand is of less than the usual height, and, as will be seen, the knot-tying and cord-severing devices are brought nearer to the breast-plate than heretofore, and by the arrangement of the parts I am enabled to bring the knife-arm through the breast-plate, so as to tie the knot nearer to the bundle than it has heretofore been tied, and by the construction and arrangement of parts shown I obtain a saving in binding-cord, and as the knot is made nearer to the bundle it has less expansion after being bound than has been heretofore obtained.

In the cutting away of the breast-plate to afford space for the cutting devices, the breastplate differs from the ordinary construction. The knife-arm is pivoted to the knotter-stand at a, from which point the arm projects downward with a sidev arm, L', extending out to the cam H, which is provided with an antifriction roller at its outer end. At or near its lower end a notch, c, is provided, through which the point of the knotter-bill passes when it is rotated, and by the use of this notch I am enabled to bring the part-s closer together and improve the compactness of the device. This knife-arm is provided with an extension, M, which acts as a cord-guide and insures the entry of the cord into or through the passage d. The knife-arm is provided also with an upward projection, N, in rear of the knotter, to which the cord-knife Z is attached.

There is sufficient space between the projections M and N for the rotation of the knotter-bill when forming the knot, and the cutter Z, by reason of its inclined form, severs the cord against the shoulder or border m of IOO the passage through the knotter-stand D. The knotter-stand may be provided at the point m with a detachable plate for renewal when Worn, if desired. The border or edge will, however, form a sufficient shoulder to enable the knife l to sever the binding-cord with ease and certainty. The'knife-arm L is also provided with a shoulder or projection, e, to which the spring f is attached. The inlner end of this spring bears upon the pin g,

which passes through the knotter-pinion and closes the movable jaw of the knotter-bill. This pin is common in this class of knotters, as is also the anti-friction wheel la at the outer end of the jaw,which presses or travels against the shoulder j and holds the j aw upon the oord while the knotter is rotating.

The wheel F is provided with a projecting ange, fi, against which the flattened portion c" of the knotter-pinion rests, and by which it is held during the major portion of the rotation of the Wheel F. This arm or ange e' is cut away over the teeth G, as shown in Fig. l, so as to permit of the rotation of the pinion 7L when the teeth G come in contact therewith. The wheel F is also provided with a scroll-tooth or ridge, o, and corresponding depressions n for rotating the cord-disk two notches at each rotation of the wheel. This Wheel is also provided around its axis with the cam-groove K, having the form shown in Fig. 3 for operating the rocker-arm R, the cam being formed in an enlarged part, J, of the Wheel F, which is partly formed in the hub F.

On the side opposite the wheel F, I place the cam-wheel H, having the cam-groove H for operating the knife-arm, which has a sidearm, L', carrying the anti-friction roller or Wheel, h, at its end. While the wheel b rests against the exterior portion of the cam-wheel, no movement of the knife-arm takes place. When it enters the cam-groove H', the knifearm is advanced so as to sever the cor'd and returned again to position, which is accomplished by the form of the cam-groove shown in detail at Fig. 7.

By pivoting the knife-arm at a and extending its operating-arm L over to the front side of the knotter, I give the arm a stronger, slower, and easier action than has heretofore been given to devices for severing the cord, and avoid the jerking or sudden action which has heretofore taken place in severing the cord and slipping the knot from the knotterbill. The slipping of the knot from the knotter-bill is also eased by the action of the diskframe P, hereinafter explained.

At the under or back side of the knife-arm I place a projection, e, (shown in Fig. 6,) to

which the spring-j is applied, so as to cause j this spring to partake of the swinging action Y of the knife-arm, and by this arrangement I give the spring a strong pressure on the pin g at the proper time, and relieve the pin from j opening and closing of the jaws, and thereby improve their action.

The disk-frame Pis suspended from the knotter-shaft T by the ears P', so that it can swing back and forth uponsaid shaft. The lower end of this frame is provided with the disk Q, which has notches on itsperiphery, as shown at Fig. 5, in one of which the bindingcord is laid by the needle-arm. This disk is provided with the spring or cord holder S,which is attached as shown in said Fig. 5, and which is provided at its lower end with a fork or side arms, S', which are also springs. The springS locks the cord within the disk Q, while the side arms of thespring S press the cord against the sides of the disk and yield to any irregularities in the cord, and also adapt themselves to any variations in the size of the cord, and by their .application I am enabled to use cords varying in size,land also poorer grades of cord, which are liable to vary in size or diameter at different parts of the same cord. This disk-frame is advanced to the knotter, as shown in Fig. 3, or made to recede therefrom, as shown in Fig. l, by the rocker-arm R, which is pivoted to a proper projection from the knotter-stand, and which is provided at its upper end with a side pin or roller, traversing the cam-groove, K, and at' its lower end with a pin projecting into a slot in the diskframe, as shown at Figs. 1 and 3. The disk- Wheel is advanced by this arrangement toward the knotter while the knot is being tied, so as to relieve the strain and also to avoid a Wastage of cord, and it is then returned to the position shown in Fig. l, while the needle-arm is back and the bundle being gathered, where it is held until grasped by the knotter, so as to give a sufficient length of cord fora proper knot, and it is then advanced to ease the strain when the knot is to be tied. It is in its return position when the cord is laid into the proper notch of the-disk Q, and While the cord is held across the disk by the needle the Wheel F is so timed that the tooth oV of the wheel F passes between two of the side teeth of the disk Q, and turns the disk to the extent of two notches, which carries the cord over between the disk and the spring S and locks it there for the return movement of the needle. The general operation of the knotter is similar to that shown in United States Letters Patent No. 333,922, so that it does not require a particular description, and by the special arrangements of the parts pointed out as new the particular action of the knotter is simpliiied and improved and its action eased, so that it has no sudden or jerking movement, and for this reason I am enabled to use inferior grades of cord.

What I claim as new, and desire to secure by Letters Patent, is
